5 Ton Mounted Knuckle Boom Marine Crane for Ship Service

FF105KC-3A is a 3-section 5-ton hydraulic knuckle boom marine crane. It weighs only 1600kg with compact folded structure to save deck space. Max lifting capacity reaches 5 ton at 2.1m radius, max working radius 8.05m, 360° full slewing and 9.8m lifting height. Hydraulic system delivers smooth operation. Standing manual control and standard base mounting holes simplify installation. Suitable for workboats, barges and aquaculture vessels to handle cargo lifting and offshore maintenance. Salt corrosion resistant option available, complete load chart provided for marine application.

FF105KC-3A 5-Ton Knuckle Boom Marine Hydraulic Crane

When selecting deck cranes for marine projects, operators often face challenges: traditional telescopic boom cranes take up significant deck space when extended and are relatively heavy, making them difficult to install on cramped decks; furthermore, it is often hard for a single crane to simultaneously handle heavy loads at close range and lighter loads at a distance. Many shipowners struggle with limited deck space, insufficient hull load-bearing capacity, and lifting coverage that falls short of operational requirements. The FF105KC-3A Marine Knuckle Boom Crane was developed specifically to address these conditions. Weighing only 1,600 kg, it features a compact stowed configuration that saves deck space. It offers a maximum lifting capacity of 5 tons (handling full loads at a 2.1-meter outreach), a maximum working radius of 8.05 meters, and a maximum lifting height of 9.8 meters, while supporting full 360° rotation. The hydraulic system ensures stable operation and smooth movement. It features manual stand-up controls and a base with standard mounting holes, simplifying shipboard installation and minimizing the need for hull modifications. Anti-corrosive salt-spray coatings are available upon request, and each unit ships with a comprehensive load chart. It is suitable for workboats, barges, and aquaculture vessels, handling tasks such as material loading/unloading, offshore equipment lifting, and near-shore maintenance. In addition to knuckle boom cranes, we supply telescopic boom cranes, grab cranes, and forestry cranes (log grapples) to meet diverse needs ranging from marine lifting and material handling to timber operations.

Product Features

1. Three-section knuckle boom structure: Lightweight with compact stowed dimensions, reducing the load on the vessel's hull and making it suitable for various vessel types with limited deck space.

2. 360° hydraulic slewing: Offers a wide operational range, adapts to both close-range and long-reach lifting scenarios, and ensures smooth, stable operation. 3. The base features pre-drilled standard mounting holes, facilitating easy installation on the vessel and reducing the time and cost associated with hull modifications.

Usage Tips

1. Consult the load chart before every lifting operation; strictly adhere to the rated load for the specific working radius and never exceed load limits.

2. When operating in offshore environments with high salt-spray levels, regularly inspect hydraulic lines and mounting bolts, and perform anti-corrosion maintenance.

3. During offshore lifting operations, be mindful of vessel motion (swaying/rolling) and operate the crane's slewing and luffing functions slowly and smoothly.

FAQ

Q1: Can this Marine Knuckle Boom Crane be installed directly onto a barge deck?

A: Yes. The base plate has pre-drilled standard mounting holes; it can be secured once the barge deck has been properly reinforced. We can provide reference drawings for installation.

Q2: What does routine maintenance entail, and how often should it be performed?

A: Routine maintenance primarily involves checking hydraulic fluid levels and seals for leaks, tightening bolts, and greasing the slewing bearing. Basic inspections are recommended monthly, and hydraulic fluid should be changed every six months; maintenance intervals should be shortened for offshore environments with high salt-spray exposure.

Q3: What after-sales support is available?

A: The equipment comes with drawings, load charts, and an operation manual. We provide remote technical guidance and can supply replacement parts separately. On-site commissioning services can be arranged upon request.

Q4: Can the crane be customized for salt-spray corrosion resistance?

A: Yes, we offer salt-spray corrosion-resistant treatments suitable for highly corrosive offshore environments to delay steel corrosion.

Q5: What are the advantages of this Knuckle Boom Crane compared to a Telescopic Boom Crane?

A: The knuckle boom crane occupies less deck space when stowed and has a lower deadweight, making it ideal for compact deck areas. While the telescopic boom crane offers a longer horizontal reach, it requires more space for stowage; customers can choose the model that best suits their deck layout and operational requirements.
